Precautions; Inspection And Maintenance - Jet JLH series Operating Instructions And Parts Manual

Do not touch the handwheel
while lifting or lowering. Do not operate
freewheel mode while there is a load on the
hoist.
5. To release or lower the load, turn selector
switch on the handle to the DOWN position
and ratchet the handle.
NOTE: If the chain is pulled too suddenly in free-
wheel mode, the brake may set preventing further
pulling. Re-set the hoist by repeating step number
3 above, and then set the hoist back into freewheel
mode to continue the operation.
Avoid lifting one load with two hoists. If this is
unavoidable, apply equal weight to both hoists and
use hoists with the proper lift capacity. Capacity of
each hoist must be equal to the total load to be
lifted.

Precautions

•
During lifting operations, do not stand under
the load.
•
Do not use any extension on the lever handle.
Do not use your foot to apply pressure to the
lever handle.
•
Prevent the chain from dragging over sharp
edges or corners. This will cause links to
weaken, bend, or break.
•
When connecting to a wire rope sling, the lever
hoist must be applied along a straight line
parallel to the surface on which it is resting.
See Figure 6.
Figure 6
•
When lifting loads, hook the load with slings.
Do not use the lever hoist chain as a sling
(Figure 7).
•
Both ends of a sling or rope must be
completely on the inside of the safety latch
before pulling or lifting the load. Do not put
one end on the inside of the latch and leave
the other end on the hook end outside the
latch.

Inspection and Maintenance

Read and follow ANSI Inspection and Maintenance
Instructions. Know the meaning of Frequent
Inspection, Periodic Inspection, Normal Service,
Heavy Service, and Severe Service. It is the
customer's responsibility to understand and follow
all ANSI and JET inspection and maintenance
instructions.
The lever hoist should be stored in a clean, dry
environment. Clean and oil the hoist before
storage.
Hoists that are installed out-of-doors should be
covered or brought inside when not in use.
Periodically apply a light coat of 30W oil to the load
chain. Also lubricate the safety latches and the
bearings in the hooks.
Annually, the hoist should be disassembled,
inspected, and cleaned by trained and experienced
personnel only. Contact a JET authorized service
center by calling your dealer or visiting our web site
at jettools.com.
